如何在grails中找到已连接的客户端IP地址

def getClientIpAddress() {
    def ipAddress = request.getHeader("X-Forwarded-For")
    if (ipAddress) {
        // 如果是代理请求，则获取第一个IP地址
        ipAddress = ipAddress.split(",")[0].trim()
    } else {
        ipAddress = request.getRemoteAddr()
    }
    return ipAddress
}

<%
    def ipAddress = request.getHeader("X-Forwarded-For")
    if (ipAddress) {
        // 如果是代理请求，则获取第一个IP地址
        ipAddress = ipAddress.split(",")[0].trim()
    } else {
        ipAddress = request.getRemoteAddr()
    }
%>
<p>客户端IP地址：${ipAddress}</p>

class ClientIpAddressFilter {
    def filters = {
        all(controller: '*', action: '*') {
            before = {
                def ipAddress = request.getHeader("X-Forwarded-For")
                if (ipAddress) {
                    // 如果是代理请求，则获取第一个IP地址
                    ipAddress = ipAddress.split(",")[0].trim()
                } else {
                    ipAddress = request.getRemoteAddr()
                }
                log.info("客户端IP地址：${ipAddress}")
            }
        }
    }
}
